The Science of Lifespan — and the Impact of Your Five Senses | Christi Gendron | TED
What you experience through your senses — sight, smell, hearing, taste and touch — can impact how healthy you are and how long you live, says neurobiologist Christi Gendron. She explores how environmental cues like temperature, light and even just the sight of death have influenced the lifespan of fruit flies, suggesting your everyday perceptions…

This has nothing to do with being closed minded. An easy way to check would have meant a global study on the ages of death of people who work in the death industry. My sample of people may be small but there are so many colleagues who have lived to a great age, if there is an effect, it will be unnoticeably tiny.

God loves you and cares for you so that this message reaches you. God is the one who created this large universe and controls it completely. The greatest loss a person loses in this life is that he lives without knowing God who created him and knowing the Messenger of Muhammad, the last of the messengers, and the Islamic religion, the last of the heavenly religions. Great intelligence, before you believe in something or not, is to read it, study it, and understand it well, and after that you have the choice to believe in it or not to believe in it. I advise you to do this now, before you no longer have time to do so. Life is very short. It is just a test, just a passage to eternal life. Great advice to those who… Understands

The sky isn’t pure black (if you define black as a complete absence of light). That’s a misperception of our inability to detect longer wavelengths of light (radiation) and weaker light sources. Even in all the space between galaxies, stars and nebulae that emit light, there’s still the cosmic microwave background that can be seen with the right equipment.

Humans have the ability to decide how we perceive aging, ill health and death.
I took care of my dying mother and at the time it felt like it could in fact kill me.
It took all my strength and determination to not let the exhaustion, emotional and physical stress kill me.
Eventually I decided to perceive it as one of the best things I’ve ever done in my life.

But in the moment when dealing with the stress of it all, imagine how people around you would have reacted to your change in mood, assuming you’re human, at some point, those moments of annoyance would of spilled out to those people, so despite your insight after the fact, those people were shaped by your interaction, small or not small, what might have come from those interactions where your frustrations spilled out 😂
@Apollo440
May 29, 2024 at 10:45 am
There is science showing that context (the way we see facts) plays an important role in how one particular circumstance influences our health. People who learn that stress is bad get worse health check results after experiencing stress. People who learn that stress is good and stimulating get better health results when being checked after experiencing stress. But there are some things which are universal and embedded in our genes: death, misery, and those things are hard to reprogram our reaction to. Meaning that you can think your way out of a situation, by diminishing the negative effects it has/had on you, but you can’t make historically bad things do you good.

Think about the longest living person documented. She lived to a 121. What did she do for a living? She was a nanny to multiple families then became a nun and worked in out reach until retiring at least 110 yrs old. What have I learned studying ultra long lived people? They have a purpose in life. In the form of a job or business that keeps them active in the community and gives them a reason to get up. Does it have to be religious work? No. I’ve met miners that worked until 95 and enjoyed it. Ditto for architects and moonshine still makers. Farmers and nazi’s, as well. They all had a purpose that got them out of bed in the morning and gave their days meaning. I’ve known dozens that worked until 65 retired(in relatively good health)and sat down and watched tv and slept in who died 6 months later…usually bitter and angry. Learn from tgese people and choose the life you’d rather live.

Interesting talk but not a new concept. This is exactly what the ancient Indian Kriya yoga methods are teaching for thousands of years. Less number of breaths leads to less agitation in the mind. Calming the mind cuts the sensory input. That gives the yogis longer lifespan than normal people. Turtle life span is longer than a rat for the same reason.

I have a question; I appreciate your research , however , you may want to look into how ants might respond to these situations. I am a key person. , but I have found , the worst thing you can do is kill an ant … it seems to attract more ants. They seem to be sacrificial animals , that live for the group and not for themselves. This seems like an important issue to factor in when you are considering first responders and those who are serving in the military. It seems as if some animals and insects are self or selfish driven and others are driven my self sacrifice for the good of the group.
I am very interested in what you might have to say about this. I would appreciate a response. Thanks.

Thomas Hunt Morgan (1933): Awarded the Nobel Prize for his discoveries concerning the role of the chromosome in heredity. Morgan conducted pioneering research on fruit flies, demonstrating that genes are located on chromosomes and are the basis of heredity…..
Edward B. Lewis (1995): Awarded the Nobel Prize, along with Christiane Nüsslein-Volhard and Eric F. Wieschaus, for their discoveries concerning the genetic control of early embryonic development using the fruit fly Drosophila melanogaster. Their work elucidated key genetic pathways involved in the development of the body plan of organisms…
Michael Rosbash, Jeffrey C. Hall, and Michael W. Young (2017): Awarded the Nobel Prize for their discoveries of molecular mechanisms controlling the circadian rhythm, using the fruit fly Drosophila melanogaster as a model organism. Their research shed light on how biological clocks regulate daily rhythms in behavior and physiology…
